Information About Resetting and Restarting Phones
Differences between Resetting and Restarting IP PhonesCisco Unified IP phones must be rebooted after configuration changes in order for the changes to be effective.Configurations for phones in Cisco Unified CME are downloaded when a phone is rebooted or reset. Youcan reboot a single phone or you can reboot all phones in a Cisco Unified CME system. The differencesbetween reboot types are summarized in Table 1: reset and restart Command Differences, on page 1.
When rebooting multiple IP phones, it is possible for a conflict to occur if too many phones attempt to accesschanged Cisco Unified CME configuration information via TFTP simultaneously.

When Required
Cisco Unified CME TAPI EnhancementBefore Cisco Unified CME 7.0(1), the only method to clear a session between a Microsoft WindowsWorkstation and an SCCP phone that was out-of-sync was to reboot the router. In Cisco Unified CME 7.0(1)and later versions, you can clear a Telephony Application Programming Interface (TAPI) session that is in afrozen state or out of synchronization by using a Cisco IOS software command. For configuration information,see Reset a Session Between a TAPI Application and an SCCP Phone, on page 5.
This enhancement also automatically handles ephone-TAPI registration error conditions. No additionalconfiguration is required for this new feature.
Reset and Restart Phones
If phones are not yet plugged in, resetting or restarting phones is not necessary. Instead, connect your IPphones to your network to boot the phone and download the required configuration files.
Note
Use the reset Command on SCCP PhonesTo reboot and reregister one or more SCCP phones, including contacting the DHCP server for updatedinformation, perform the following steps.
